$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\)	\(=\)	\( q + (2 \zeta_{6} - 2) q^{2} + 5 \zeta_{6} q^{3} - 4 \zeta_{6} q^{4} + ( - 9 \zeta_{6} + 9) q^{5} - 10 q^{6} + ( - 14 \zeta_{6} - 7) q^{7} + 8 q^{8} + ( - 2 \zeta_{6} + 2) q^{9} +O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 2 q - 2 q^{2} + 5 q^{3} - 4 q^{4} + 9 q^{5} - 20 q^{6} - 28 q^{7} + 16 q^{8} + 2 q^{9}+O(q^{10}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/14\mathbb{Z}\right)^\times\).

\(n\)	\(3\)
\(\chi(n)\)	\(-1 + \zeta_{6}\)
